aurora – Header files for dvips to make colour separations

Off­set print­ers need sep­a­rate cam­era-ready copies for each ink
they will use in print­ing a doc­u­ment. Aurora is a PostScript
pro­gram for pro­duc­ing colour sep­a­rates from a colour PostScript
doc­u­ment. Aurora can be run from any type of com­puter, as it
de­pends only on a black-and-white PostScript printer for its
ex­e­cu­tion. It is ca­pa­ble of han­dling colour im­ages as well as
or­di­nary graph­ics, though im­age han­dling is very slow.
